math f1 (20點) 邊個解得詳細就邊個攞果20點!

Production Rate of Machine A (toy car/hour) is:
(5x+1)/2

Production Rate of Machine B (toy car/hour) is:
(7x+10)/3

Number of toy car after 6 hours of Machine A=Number of toy car after 6 hours of Machine B

i.e., 6*[(5x+1)/2] = 6*[(7x+10)/3]
15x+3 = 14x+20
x=17

So, toys cars can be produced in total by the two machine after 6 hours is
6*[(5x+1)/2] + 6*[(7x+10)/3] for x=17
29x+23=516

HENCE, ANSWER IS 516.
